Absolute con. Have been paying on the machine in Shenfield Station, never gives a receipt but says 'payment successful'. Did not check my bank, why would I (although I do now and screen shot). I started receiving tickets in November going back to August. Appealed them due to length of time and NCP stated 'they can do what they want!'. Done an online chat on 12th Dec and told there were only 4 PCNs. I have now received about 20 predating this chat and when I checked none of the payments have come out of my bank. I now screen shot the payment or pay online (which does seem to work). Have appealed and they have refused the appeals and I reckon by the time this has finished I will have over £3,000 in fines. NCP wont check the machine and wont help. I cannot afford to pay these fines and in good faith I thought I had paid. You cannot take to ombudsman as if you do this to POPLA you have to either risk a £100 fine and if you have already paid you cannot appeal. One of the fines was for a partial payment, which you cannot even do as it tells you what to pay! So disgusted
